Electrical Safety

Observe the following safety instructions any time you are connecting or disconnecting
devices attached to the server.

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the devices that attach to the system. It is the
responsibility of the customer to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock.

Before installing or removing signal cables, ensure that the power cables for
the system unit and all attached devices are unplugged.

When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables to
prevent a possible shock from touching two surfaces with different electrical
potentials.

During an electrical storm, do not connect cables for display stations, printers,
telephones, or station protectors for communications lines.

CAUTION:
This product is equipped with a three–wire power cable and plug for the user’s
safety. Use this power cable with a properly grounded electrical outlet to avoid
electrical shock.

Laser Safety Information

CAUTION:
This product may contain a CD-ROM which is a class 1 laser product.

Laser Compliance

All lasers are certified in the U.S. to conform to the requirements of DHHS 21 CFR
Subchapter J for class 1 laser products. Outside the U.S., they are certified to be in
compliance with the IEC 825 (first edition 1984) as a class 1 laser product. Consult the
label on each part for laser certification numbers and approval information.

xii Service Guide

CAUTION:
All IBM laser modules are designed so that there is never any human access to
laser radiation above a class 1 level during normal operation, user maintenance,
or prescribed service conditions. Data processing environments can contain
equipment transmitting on system links with laser modules that operate at
greater than class 1 power levels. For this reason, never look into the end of an
optical fiber cable or open receptacle. Only trained service personnel should
perform the inspection or repair of optical fiber cable assemblies and receptacles.

Preface xiii

xiv Service Guide

Data Integrity and Verification

IBM computer systems contain mechanisms designed to reduce the possibility of
undetected data corruption or loss. This risk, however, cannot be eliminated. Users who
experience unplanned outages, system failures, power fluctuations or outages, or
component failures must verify the accuracy of operations performed and data saved or
transmitted by the system at or near the time of the outage or failure. In addition, users
must establish procedures to ensure that there is independent data verification before
relying on such data in sensitive or critical operations. Users should periodically check
the IBM support websites for updated information and fixes applicable to the system and
related software.

Powering Off and Powering On the System

This section provides procedures for powering off and powering on the system.

Powering Off the System

If the system is operating under AIX, type the shutdown command to power off the
system.

If you cannot use this method, you can power off the system by using the following
operator-panel power button procedure:

Attention: Using the operator-panel power button to power off the system might
cause unpredictable results in the data files, and the next IPL will take longer to
complete.

1. Open the access door.

2. Press the power button on the operator panel.
B0FF appears in the operator panel display. The operator panel power LED starts

blinking at a fast rate.

When the power-off sequence is complete, the system goes into standby power mode,
as evidenced by the following:

v OK displays in the operator panel display.
v The operator panel power LED starts blinking at a slow rate.

Powering On the System

Perform the following steps to power on the system:

1. Open the access door. Look for OK on the operator panel display, which indicates
that the system is in standby mode.

2. Press the power button on the operator panel.
The power LED on the operator panel starts blinking at a fast rate. Checkpoint

codes (9xxx) appear in the operator panel display. For details, see “IPL Flow” on
page 83.

When the power-on sequence is complete, the power LED on the operator panel stops
blinking and stays on.

Powering Off and Powering On the System Using the Service Processor

The system can be powered off and on using the System Power Control menu, which is
a service processor menu that is available to the privileged user. See “System Power
Control Menu” on page 260.

Chapter 1. Reference Information 9

Console Strategy

The firmware starts a console-selection sequence at system boot time if any of the
following is true:

v A console has not yet been selected.
v A previous console selection sequence timed out.
v A change in the system configuration affects the console (keyboard

installed/removed, mouse installed/removed, graphics adapter installed/removed or
moved to another PCI slot).

The console-selection sequence allows you to select (from the appropriate input device)
one of the available console devices. If no console is selected within approximately 60
seconds, serial port 1 (S1) is selected as the console and the selection sequence times
out.

After a console has been selected, the console-selection sequence is only started at
boot time if there is a change in the system configuration (as described above), or the
contents of the system’s nonvolatile memory (NVRAM) are lost.

Note: Moving an ASCII terminal from one serial port to another (from S1 to S2) cannot

be detected by the firmware, so it does not constitute a configuration change.

You can also initiate a firmware console selection sequence from the System
Management Services (SMS) menus.

Power-On Self-Test

After power is turned on and before the operating system is loaded, the system does a
power-on self-test (POST). This test performs checks to ensure that the hardware is
functioning correctly before the operating system is loaded. During the POST, a POST
screen displays and POST indicators appear on the fimware console (if one is
connected). The next section describes the POST indicators and functions that can be
accessed during the POST.

POST Indicators

POST (power-on self-test) indicators indicate tests that are being performed as the
system is preparing to load the operating system. The POST indicators are words that
display on the system console. Each time that the system starts another step in the
POST, a POST indicator word appears on the console. Each word is an indicator of the
tests that are being performed.

10 Service Guide

The POST screen displays the following words:

Memory Memory test
Keyboard Initialize the keyboard and mouse. The window for pressing a key to

access the System Management Services, or to initiate a service
mode boot, is now open. See “POST Keys” for more information.

Network Self-test on network adapters
SCSI Adapters are being initialized
Speaker Sounds an audible tone at the end of POST

POST Keys

The POST keys, if pressed

after

the keyboard POST indicator displays and

before

the
last POST indicator (speaker) displays, cause the system to start services or to initiate
service mode boots used for configuring the system and diagnosing problems. The keys
are described below:

Note: The program function keys (F1-F12) on a keyboard attached to the system unit

are no longer used and will be ignored during POST. After the keyboard POST
indicator displays, you must use the numeric number keys to enter input.

1 Key

The numeric 1 key, when pressed during POST, starts the System Management
Services (SMS) interface.

5 Key

The numeric 5 key, when pressed during POST, initiates a system boot in service mode
using the default service mode boot list.

This mode attempts to boot from the first device of each type found in the list. It does
not search for other bootable devices of that type if the first device is not bootable.
Instead, it continues to the next device type in the list. The firmware supports up to five
entries in the boot list.

The default boot sequence is:

1. Diskette

2. CD-ROM

3. Hard file

4. Tape drive (if installed)

5. Network

a. Token ring
b. Ethernet

Chapter 1. Reference Information 11

6 Key

The numeric 6 key works like the numeric 5 key, except that firmware uses the
customized service mode bootlist that was set up using the AIX service aids.

8 Key

To enter the open firmware command line, press the numeric 8 key

after

the word
keyboard displays and before the last word (speaker) displays during startup. After you
press the 8 key, the remaining POST indicators display until initialization completes.

When initialization and POST are complete, the open firmware command line (an OK
prompt) displays.

The open firmware command line should only be used by service personnel to obtain
additional debug information.

To exit from the open firmware command prompt, type reset-all or power off the
system and reboot.

processor resets and then shuts down the system.

System Memory

Two slots are available for memory riser cards. Each riser card had 16 sockets. See
“System Board” on page 15, which illustrates the positions of the memory riser cards in
the system.

Four sizes of DIMMs are available: 128 MB, 256 MB, 512 MB, and 1 GB. Certain 32
MB DIMMs from older RS/6000 systems can also be used when upgrading system
memory.

One-Way Processor Memory Placement Rules

The rules for one-way processor memory are as follows:
v Minimum memory is 1 pair of DIMMs in slots 1 and 8 (see “Processor Card Memory

DIMM Locations for Service Processor Menus” on page 270).

v Maximum memory is 4 DIMM pairs in slots 1 through 8 (see “Processor Card

Memory DIMM Locations for Service Processor Menus” on page 270).

v Each memory riser slot must have a memory filler card installed.

16 Service Guide

v When you are installing a memory riser card:

– Memory DIMMs must be moved from the one-way processor card to the memory

riser card.

– The memory riser card must then have a minimum of 1 quad (four DIMMs).

Riser Card Memory Placement Rules

The rules for memory riser cards are as follows:

v Memory quads must contain DIMMs of equal memory size.
v Quad memory size may be mixed on a riser card.
v The minimum memory is four DIMMs, which must occupy quad A, slots 1, 2, 15 and

16 (see “Memory Riser Card and Memory DIMM Locations” on page 23).

v Populate the riser card starting with quad A and continuing with quads B, C, and D

(see “Memory Riser Card and Memory DIMM Locations” on page 23).

Logical and Physical Locations

This system uses physical location codes in conjunction with AIX location codes to
provide mapping of the failing field replaceable units (FRUs). The location codes are
produced by the system unit’s firmware and the AIX operating system.

Physical Location Codes

Physical location codes provide a mapping of logical functions in a platform (or
expansion sites for logical functions, such as connectors or ports) to their specific
locations within the physical structure of the platform.

Location Code Format

The format for the location code is a string of alphanumeric characters separated by a
dash (–), slash (/), pound sign (#) or period (·) character. The base location is all of the
information preceding the slash (/) or pound sign (#). The base location identifies a
device that is connected to or plugged into the parent. Extended location information
follows the slash (/). Extended location information identifies a device that is part of the
parent, a connector, or a cable. Cable information follows the pound sign (#). Cable
information identifies a cable that is connector to parent. The following are examples:

v P1-C1 identifies a processor card C1 plugged into planar P1.
v P1-M1 identifies a memory riser card M1 plugged into planar P1.
v P-1-Z1-A3 identifies a SCSI device with SCSI ID 3 attached to SCSI bus 1 on planar

1.

v P1-K1 identifies a keyboard attached to K1 on planar P1.
v P1/S1 identifies serial port 1 controller on planar P1, the connector for serial port 1,

or the cable attached to serial port 1.

v P1-I2/E3 identifies an Ethernet controller 3, on the card in slot 2 (I2) on planar P1,

the connector for Ethernet controller 3, or the cable attached to Ethernet controller 3.

v P1-I2#E3 identifies the cable attached to Ethernet controller 3 on the card in slot 2

(I2) on planar P1.

Chapter 1. Reference Information 17

The period (·) identifies sublocations (DIMMs on a memory riser card, SCSI addresses,
cables). The following are examples:

v P1-M1.4 identifies DIMM 4 on memory riser card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.
v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3

attached to SCSI bus 1 from planar 2.

v P1-I2#E3.2 identifies the second in a series of cables attached to Ethernet controller

3 on the card in slot 2 (I2) on planar P1.

Depending on the AIX and firmware levels, AIX diagnostics may include the extended
location information when identifying a planar or card. The extended location
information or cable information is always included when identifying a cable or
connector. Location codes with extended location information that are displayed without
a description identifying the devices always identify the cable attached to the port.

Multiple FRU Callout Instructions

If an eight-digit error code appears in the operator panel display or as described in
Chapter 5, “Error Code to FRU Index” on page 105, a location code for a failing part
may also be specified. If the location code includes a blank space followed by a
lowercase x followed by a number, this is an error code with multiple FRU callouts. This
error can typically happen with memory DIMMs, memory riser cards, or processors and
may involve mixed types of parts. In this case, check the system’s configuration for
FRU part numbers to determine the appropriate set of FRUs.

For example, if the location code P1-M1.1 x2 was displayed, this indicates memory pair
A (two DIMMs) on the first memory riser card was suspected.

You can determine the FRU part numbers of the electronic assemblies in the system in
two ways:

v Using the service processor menus

From the general user menu, select Read VPD Image from Last System Boot,
then enter 90 to display detailed vital product data (VPD).

v Typing the lscfg -vp | pg command on the AIX command line

Type the following command: lscfg -vp | pg to display the detailed VPD of all
assemblies. Notice that the FRU part number information for processors and memory
DIMMs may be at the bottom of the command output.

18 Service Guide

AIX Location Codes

The basic formats of the AIX location codes are as follows:
v For non-SCSI devices/drives:

– AB-CD-EF-GH

v For SCSI devices/drives:

– AB-CD-EF-G,H

For planars, cards, and non-SCSI devices, the location code is defined as follows:

AB-CD-EF-GH

||||
| | | Device/FRU/Port ID
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus

v The AB value identifies a bus type or PCI parent bus as assigned by the firmware.
v The CD value identifies adapter number, adapter’s devfunc number, or physical

location. The

devfunc

number is defined as the PCI device number times 8, plus the

function number.

v The EF value identifies a connector.
v The GH value identifies a port, address, device, or FRU.

Adapters and cards are identified only with AB-CD.

The possible values for CD depend on the adapter/card. For pluggable PCI
adapters/cards, CD is the device’s devfunc number (PCI device number times 8, plus
the function number). The C and D are characters in the range of 0-9, and A-F (hex
numbers). The location codes therefore uniquely identify multiple adapters on individual
PCI cards.

EF is the connector ID, used to identify the adapter’s connector to which a resource is
attached.

GH is used to identify a port, device, or FRU. For example:

v For async devices, GH defines the port on the fanout box. The values are 00 to 15.
v For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.
v For all other devices, GH is equal to 00.

For integrated adapter, EF-GH is the same as the definition for a pluggable adapter. For
example, the location code for a diskette drive is 01-D1-00-00. A second diskette drive
is 01-D1-00-01.

Chapter 1. Reference Information 19

For SCSI devices, the location code is defined as follows:

AB-CD-EF-G,H

| | |||
| | | | Logical Unit address of the SCSI Device
| | | Control Unit Address of the SCSI Device
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus

AB-CD-EF are the same as non-SCSI devices.

G defines the control unit address of the device. Values of 0 to 15 are valid.

H defines the logical unit address of the device. Values of 0 to 255 are valid.

A bus location code is also generated as 00-XXXXXXXX, where XXXXXXXX is
equivalent to the node’s unit address.

Examples of physical location codes and AIX location codes are:

v PCI adapter in Slot 1
v Location code P1-I1
v AIX location code 20-58

Notes:

1. The physical location code for the PCI slots, when empty, uses the P1/Ix notation,
where the ’/’ identifies an integrated device (in this case the empty slot). A PCI
device plugged into the slot uses the P1-Ix notation, where the ’–’ identifies a
plugged device.

2. 11 is for the integrated SCSI device. -4,0 and -2,0 are hardcoded on the DASD
2-pack; -0,0 is the tape drive; -1,0 is the CD-ROM.

3. xx-xx is dependent on which SCSI controller is driving the 6-pack.

4. Use the link verification utility in the SSA service aids under AIX diagnostics to
identify individual SSA drives.

32 Service Guide

Service Inspection Guide

Perform a service inspection on the server when:

v The server is inspected for a maintenance agreement.
v Service is requested and service has not recently been performed.
v An alterations and attachments review is performed.
v Changes have been made to the equipment that may affect the safe operation of the

equipment.

v External devices with their own power cables have those cables attached.

If the inspection indicates an unacceptable safety condition, the condition must be
corrected before anyone can service the machine.

Note: The owner of the server is responsible to correct any unsafe condition.

Perform the following checks:

1. Check the covers for sharp edges and for damage or alterations that expose the
internal parts of the server unit.

2. Check the covers for proper fit to the server unit. They should be in place and
secure.

3. Perform the appropriate power-off procedures.

4. Open the covers.

5. Check for alterations or attachments. If there are any, check for obvious safety
hazards, such as broken wires, sharp edges, or broken insulation.

6. Check the internal cables for damage.

7. Check for dirt, water, and any other contamination within the server unit.

8. Check the voltage label on the back of the server unit to ensure that it matches the
voltage at the outlet.

9. Check the external power cable for damage.

10. With the external power cable connected to the server unit, check for 0.1 ohm or
less resistance between the ground lug on the external power cable plug and the
metal frame.

11. Perform the following checks on each device that has its own power cables:

a. Check for damage to the power cord.
b. Check for the correct grounded power cable.
c. With the external power cable connected to the device, check for 0.1 ohm or

less resistance between the ground lug on the external power cable plug and

Chapter 2. Diagnostics Overview

Models F80, 6F0, and 6F1 systems use an integrated set of software diagnostic
procedures to facilitate isolation of failing components and system maintenance. This
book, along with the

RS/6000 and

Eserver

pSeries Diagnostic Information for Multiple

Bus Systems

, are the basis of the diagnostic procedures for Models F80, 6F0, and 6F1
systems. In particular, the following sections in this book are important for the trained
service representative to understand and use when isolating a failure on the system:

v Chapter 4, “Checkpoints” on page 83
v Chapter 5, “Error Code to FRU Index” on page 105
v Chapter 6, “Loading the System Diagnostics In Service Mode” on page 249
v Chapter 10, “Parts Information” on page 377

The manufacturer recommends that systems configured with 4 GB of memory or
greater have access toa4mmor8mmtape drive for submission of system dump
information if required. This function can be accomplished through locally attached or
network-attached devices, as appropriate.

Maintenance Analysis Procedures (MAPs)

Maintenance analysis procedures (MAPs) guide the trained service person through the
system. These MAPs are the entry point for all isolation and error-recovery procedures.
The MAPs are consistent with existing procedures and methods. The system uses a set
of integrated procedures, mentioned earlier, to which the MAPS are the primary entry
point.

The MAPS are as follows:

v Entry MAP
v Quick Entry MAP
v Problem Determination MAP
v Power MAP
v Minimum Configuration MAP

The Entry Map is the starting point for problem determination. The purpose of this MAP
is to quickly point to the appropriate MAP or service reference information either in this
book, or in the common book set, which includes the

RS/6000 and

Eserver

pSeries

Diagnostic Information for Multiple Bus Systems

and the

PCI Adapter Placement

Reference

.

The Quick Entry MAP is a subset of the Entry MAP and helps to save time for some
types of problems.

The Problem Determination MAP provides a structured analysis method to get an error
code if one is not provided by the customer, or if diagnostics cannot be loaded.

35

The Power MAP deals with isolation of components to diagnose a power problem. The
nature of power problems can be related to powering on and down the system, or
power failures that can occur after power is turned on.

The Minimum Configuration MAP is used to locate defective components not found by
normal diagnostics or error-isolation methods. This MAP provides a systematic method
of isolation to the failing item or items.

Checkpoints

These servers use various types of checkpoints, error codes, and SRNs, which are
referred to throughout this book (primarily in Chapter 4, “Checkpoints” on page 83,
Chapter 5, “Error Code to FRU Index” on page 105, Chapter 6, “Loading the System
Diagnostics In Service Mode” on page 249, and Chapter 10, “Parts Information” on
page 377). These codes may appear in the service processor boot progress log, the
AIX error log, and the operator panel display. Understanding the definition and
relationships of these codes is important to the service personnel who are installing or
maintaining these servers.

Codes that can appear on the operator panel or in error logs are as follows:

Checkpoints

Checkpoints display in the operator panel from the time ac power (dc power in
a dc-powered system) is connected to the system until the AIX login prompt is
displayed after a successful operating system boot. These checkpoints have
the following forms:

8xxx 8xxx checkpoints display from the time ac power (dc power in a

dc-powered system) is connected to the system until the OK prompt is
displayed by the service processor on the operator panel display.
(Several 9xxx checkpoints are displayed just before the OK prompt
displays.)

9xxx 9xxx checkpoints are displayed by the service processor after the

power-on sequence is initiated. A system processor takes over control
when 91FF displays on the operator panel.

Exxx Exxx checkpoints indicate that a system processor is in control and is

initializing the system resources. Control is being passed to AIX when
E105 (normal mode boot) or E15B (service mode boot) displays on the
operator panel.

Note: Location code information may also display on the operator

panel during this time.

0xxx 0xxx codes are AIX checkpoints and configuration codes. Location

codes may also be shown on the operator panel display during this
time.

2xxx 2xxx codes are AIX checkpoints and configuration codes. Location

codes may also be shown on the operator panel display during this
time.

36 Service Guide

Note: Certain checkpoints may remain in the display for long periods of time.

A spinning cursor is visible in the upper-right corner of the display
during these periods to indicate that system activity is continuing.

Error Codes

If a fault is detected, an 8-digit error code is displayed in the operator panel
display. A location may be displayed at the same time on the second line of
the display.

Checkpoints can become error codes if the system fails to advance past the
point at which the code was presented.

For a list of checkpoints, see Chapter 4, “Checkpoints” on page 83. Each entry
provides a description of the event and the recommended action if the system
fails to advance.

SRNs Service request numbers, in the form xxx-xxx or xxx-xxxx, may also be

displayed on the operator panel display and be noted in the AIX error log.
SRNs are listed in the

FRU Isolation

For a list of error codes and recommended actions for each code, see Chapter 5, “Error
Code to FRU Index” on page 105. These actions can refer to Chapter 10, “Parts
Information” on page 377, Chapter 3, “Maintenance Analysis Procedures (MAPs)” on
page 41, or provide informational message and directions. If a replacement part is
indicated, direct reference is made to the part name. The respective AIX and physical
location codes are listed for each occurrence as required. For a list of locations codes,
see “AIX and Physical Location Code Reference Tables” on page 21.

To look up part numbers and view component diagrams, see Chapter 10, “Parts
Information” on page 377. The beginning of the chapter provides a parts index with the
predominant field replaceable units (FRUs) listed by name. The remainder of the
chapter provides illustrations of the various assemblies and components which make up
these servers.

Electronic Service Agent for the Eserver pSeries and RS/6000

Service support for your system can be enhanced through the use of the application
program, Electronic Service Agent. This application provides a number of advantages
for the systems customer, including automatic error reporting and analysis without
customer intervention. The Electronic Service Agent kit includes the

Electronic Service

Agent for

Eserver

pSeries and RS/6000

CD, order number LCD4–1060, which

contains documentation to help you set up and use Electronic Service Agent.

Chapter 2. Diagnostics Overview 37

Using the Service Processor and Electronic Service Agent Features

The service processor and Electronic Service Agent features protect users against
unnecessary system downtime by advising support personnel (both internal and
external) of any unexpected changes in the system environment. In combination, the
two features provide a flexible solution to automated system maintenance.

Service Processor

The service processor runs on its own power boundary and continually monitors
hardware attributes, the AIX operating system, and the environmental conditions within
the system. Any system failure which prevents the system from returning to an
operational state (a fully functional AIX operating system) is reported by the service
processor. The service processor is controlled by firmware and does not require the AIX
operating system to be operational to perform its tasks. If any system failures are
detected, the service processor has the ability to take predetermined corrective actions.
The methods of corrective actions are:

v Surveillance
v Call home
v AIX operating system monitoring

Surveillance is a function in which the service processor monitors the system through

heartbeat

communication with the system firmware. The heartbeat is a periodic signal
that the firmware can monitor. During system startup, the firmware surveillance monitor
is automatically enabled to check for heartbeats from the firmware. If a heartbeat is not
detected within a default period, the service processor cycles the system power and
attempts to restart until the system either restarts successfully, or a predetermined retry
threshold is reached. In the event the service processor is unsuccessful in bringing the
system online (or in the event that the user asked to be alerted to any service
processor-assisted restarts), the system can call home to report the error.

The call home function can be initialized to call either a service center telephone
number, a customer administration center, or a digital pager telephone number. The
service processor can be configured to stop at the first successful call to any of the
numbers listed, or can be configured to call every number provided. If connected to the
service center, the service processor transmits the relevant system information (the
system’s serial number and model type) and service request number (SRN). If
connected to a digital pager service, the service processor inputs a customer voice
telephone number defined by the customer. An established sequence of digits or the
telephone number to a phone near the failed system could be used to signal a system
administrator to a potential system failure.

During normal operations, the service processor can also be configured to monitor the
AIX operating system. If AIX does not respond to the service processor heartbeat, the
service processor assumes the operating system is hung. The service processor can
automatically initiate a restart and, if enabled, initiate the call home function to alert the
appropriate people to the system hang. Enabling operating system surveillance also
enables AIX detect any service processor failures and report those failures to the
Electronic Service Agent application.

38 Service Guide

Unlike the Electronic Service Agent, the service processor cannot be configured in a
client/server environment where one system can be used to manage all dial-out
functions for a set of systems.

Prior to installing the Electronic Service Agent feature, ensure that you have the latest
level of system firmware. You also need a properly configured modem. For more
information on configuring a modem, see “Modem Configuration Menu” on page 274.

Electronic Service Agent

The Electronic Service Agent is a software extension to the AIX operating system that
monitors the system while the AIX operating system is running. The Electronic Service
Agent monitors and analyzes all recoverable system failures, and, if needed, can
automatically place a service call to a service center (without user intervention).

The service center receives the machine type/serial number, host name, SRN, and a
problem description. The service center analyzes the problem report and, if warranted,
dispatches a service person to the customer site. The service center also determines if
any hardware components need to be ordered prior to the service person’s arrival.

The Electronic Service Agent code also gives the user the option to establish a single
system as the problem reporting server. A single system, accessible over the user
network, can be used as the central server for all the other systems on the local area
network (LAN) that are running the Electronic Service Agent application. If the
Electronic Service Agent application on a remote client decides a service request needs
to be placed, the client forwards the information to the Electronic Service Agent server
that dials the service center telephone number from its locally attached modem. In this
scenario, the user only needs to maintain a single analog line for providing call-out
capabilities for a large set of servers.

When used in a scalable parallel (SP) environment, a client/server type implementation
is configured. The Electronic Service Agent client code runs on each of the SP nodes.
The server component runs on the control workstation. In the event of any system
failures, the relevant information is transmitted to the control workstation through the
integrated Ethernet. After it has been alerted to the system failure, the control
workstation initiates actions to prepare and send the service request.

A modem is required for enabling automated problem reporting to the service center.
Configuration files for several types of modems are included as part of the Electronic
Service Agent package. Refer to “Modem Configuration Menu” on page 274 for more
information on configuring your modem.

Chapter 3. Maintenance Analysis Procedures (MAPs)

This chapter contains maintenance analysis procedures (MAPs) for the Models F80,
6F0, and 6F1 systems.

Entry MAP

Use the following table to determine your starting point.

When possible, run online diagnostics in service mode. Online diagnostics perform
additional functions, compared to standalone diagnostics. This ensures that the error
state of the system is captured in NVRAM for your use in fixing the problem. The AIX
error log and SMIT are only available when diagnostics are run from the hard drive.

Notes:

1. If more than eight digits are displayed in the top line of the operator panel display,
use only the first eight digits to find the error in the tables. The digits that display
beyond the first eight digits are location codes that can assist you in diagnosing the
problem. See “AIX and Physical Location Code Reference Tables” on page 21.

2. Licensed programs frequently rely on system information stored on the VPD module
on the operator panel assembly. If the MAPs indicate that the operator panel
assembly should be replaced, swap the VPD module from the old operator panel to
the new one. If the old VPD module has to be replaced, call technical support for
recovery instructions. If recovery is not possible, notify the system owner that new
keys for licensed programs may be required.

3. If a network adapter or the system board is replaced, the network administrator
must be notified so that the client IP addresses used by the server can be changed.
In addition, the operating system configuration of the network controller may need to
be changed in order to enable system startup. Also check to ensure that any client
or server that addresses this system is updated.

MAP 1540: Minimum Configuration

Purpose of this MAP

This MAP is used to locate defective FRUs not found by normal diagnostics. For this
procedure, diagnostics are run on a minimally configured system. If a failure is detected
on the minimally configured system, the remaining FRUs are exchanged one at a time
until the failing FRU is identified. If a failure is not detected, FRUs are added back until
the failure occurs. The failure is then isolated to the failing FRU.

Notes:

1. Be sure to unplug the power cable before removing or installing the processor card,
memory riser card(s), or system board to avoid damage to them.

2. This MAP assumes that a CD-ROM drive is installed and connected to the
integrated SCSI adapter, and a Diagnostics CD-ROM is available.

3. If a power-on password or privileged-access password is installed, you are
prompted to enter the password before the diagnostic CD-ROM can load.

4. The term

POST indicators

refers to the device mnemonics (words memory,
keyboard, network, scsi, and speaker) that appear during the power-on self-test
(POST).

Chapter 3. Maintenance Analysis Procedures 57

5. The service processor may have recorded one or more symptoms in its error log. It
is a good idea to examine that error log before proceeding (see Service Processor
System Information Menu).

6. The service processor may have been set by the user to monitor server operations
and to attempt recoveries. You can disable these actions while you diagnose and
service the system. If you disable them, make notes of their current settings so that
you can restore them easily. The following table lists the settings:

Surveillance From the Service Processor Setup Menu, go to

the Surveillance Setup Menu and disable
surveillance.

Unattended Start From the Service Processor System Power

Control Menu, disable unattended start mode.

Reboot Policy From the System Power Control Menu, go to

the Reboot/Restart Policy Setup Menu and set:
a. Number of reboot attempts to 0 (zero)
b. Use OS-Defined restart policy to No
c. Enable supplemental restart policy to No.

SSA Maintenance Analysis Procedures (MAPs)

These maintenance analysis procedures (MAPs) describe how to analyze a continuous
failure that has occurred in a system that contains two or more disk drive modules.
Failing field-replaceable units (FRUs) of the system unit can be isolated with these
MAPs.

Using SSA MAPs

Attention: Turning off the power to an SSA hot-swap disk drive can cause a system

fault unless you first make the SSA hot-swap disk drive modules unavailable to the
system unit. To do this:

1. Use the system-management task menus to make the disk drive modules
unavailable.

2. If the system unit has more than one SSA adapter, make the SSA hot-swap disk
drive modules unavailable to the system for each of the paths to the SSA hot-swap
disk drive.

Attention: Unless the system unit must be turned off for some other reason,

do not
turn off the power to the system unit when servicing an SSA hot-swap disk drive or the
external SSA cable

.

v To isolate the FRUs associated within the failing SSA hot-swap disk drive, perform

the actions and answer the questions given in this MAP.

v When you are instructed to exchange two or more FRUs in sequence, do the

following:

1. Exchange the first FRU in the list for a new one.

2. Verify that the problem is solved. For some problems, verification means running
the diagnostic programs (see the using-system service procedures).

3. If the problem remains:
a. Reinstall the original FRU.
b. Exchange the next FRU in the list for a new one.

4. Repeat steps 2 and 3 until either the problem is solved, or all the related FRUs
have been exchanged.

Chapter 3. Maintenance Analysis Procedures 75

5. Perform the next action indicated by the MAP.

SSA disk drives have light emitting diodes (LEDs) to identify the state of the disk
drive (1) shown in the following diagram.

MAP 2323: SSA hot-swap disk drive Intermittent Link Verification

This MAP helps you isolate FRUs that are causing an intermittent SSA link problem.
You are here because you have an SRN from the series 21xxx through 29xxx, or you
have SRN 33xx.

If you are not familiar with the SSA link, go to “SSA Loops and Links” on page 438.

Attention: Unless the system needs to be switched off for some other reason,

do not

turn off the system when servicing the SSA loop.

Step 2323-1

1. Run the Link Verification service aid to the SSA adapter for which the error has
been logged. A list of pdisks is displayed.

Note: On the Link Verification screen, each adapter port is identified by the number

of its related connector on the adapter card, as follows:

v Adapter port 0 is identified as A1
v Adapter port 1 is identified as A2
v Adapter port 2 is identified as B1
v Adapter port 3 is identified as B2

SRNs 21xxx through 29xxx and SRN 33xxx include the adapter port number
(0-3).

2. Go to “Step 2323-2”.

Step 2323-2

1. Observe the SRN that sent you to this MAP. The last three characters are in the
format

PAA

, wherePis the number of the SSA adapter port, and

AA

is the SAA

address of the device.
Note the value of

PAA

in the SRN. For example:

v If the SRN is 24002,

PAA

= 002.

v If the SRN is 24104,

PAA

= 104.

2. Observe the Link Verification screen, and identify the physical device that is
represented by

PAA

in the SRN. This device is the first of the two devices that are

connected by the failing link.
If the SRN is in the series 21xxx through 29xxx, the second device of two is located

at

PAA

-1.

80 Service Guide

If the SRN is 33xxx, the second device of the two is located at

PAA

+1.

Note: If the SSA address (

AA

) in the SRN is higher than the highest SSA address

that is displayed for the adapter port (

P

), that address is the address of the

SSA adapter.

3. Go to “Step 2323-3”.
